We do not recommend to fog for termites in a crawl space. It will not penetrate the raw wood. In this case we recommend to treat using Boracare. Boracare will penetrate up to 4 inches into the wood and will last the lifetime of the wood. You can paint it, spray it, or foam it onto the raw wood. Please take a few moments to review our treatment article on How to Treat for Termites for more information.
